Answer:
Explanation:
a ) radius of star R = 18 x 10³ m
time period of rotation T = .86 s.
angular velocity ω = 2π / T
= 2 X 3.14 / .86
= 7.3 radian / s .
velocity required
= ω R
7.3 x 18 x 10³
= 131.4 m /s
b )
centripetal acceleration
= ω² R
= ω R ω
= 131.4 x 7.3
959.22 m/s²
c )
If the neutron star rotates faster , both velocity of the particle on the equator
and centripetal acceleration increases.
Answer:
Two objects will have the equal velocities but the forces on both of them will not be equal. The equal velocities of these objects are due to their equal acceleration.
Explanation:
From the newton's equation
![v^{2} -u^{2} = 2as](https://tex.z-dn.net/?f=v%5E%7B2%7D%20-u%5E%7B2%7D%20%3D%202as)
so here we can say that velocity does not depends on the mass.
The acceleration of both objects will be same but not the forces because
F = Ma
As the force is depending on the mass so it will not be the same for both objects.

Answer:
F = 3.2 x 10⁻⁵ N
Explanation:
The gravitational force of attraction between the two objects is given by Newton's Gravitational law through the following formula:
where,
F = gravitational force = ?
G = Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²
m₁ = mass of object 1 = 235 kg
m₂ = mass of object 2 = 1.37 x 10¹² kg
r = distance between objects = 2.59 x 10⁴ m
Therefore,
![F = \frac{(6.67\ x\ 10^{-11}\ Nm^{2}/kg^{2})(235\ kg)(1.37\ x\ 10^{12}\ kg)}{(2.59\ x\ 10^{4}\ m)^{2}}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7B%286.67%5C%20x%5C%2010%5E%7B-11%7D%5C%20Nm%5E%7B2%7D%2Fkg%5E%7B2%7D%29%28235%5C%20kg%29%281.37%5C%20x%5C%2010%5E%7B12%7D%5C%20kg%29%7D%7B%282.59%5C%20x%5C%2010%5E%7B4%7D%5C%20m%29%5E%7B2%7D%7D)
